$ RUN SYS$SYSTEM:SYSMAN
SYSMAN> PARAMETERS USE CURRENT
SYSMAN> PARAMETERS SET STARTUP_P1 ""
SYSMAN> PARAMETERS WRITE CURRENT
Caution
If you boot with minimum startup with the VAXCLUSTER system
parameter set to 0, the only HSC or DSSI devices that will be accessible
will be the boot device and then only if the boot device is controlled by an
HSC or a DSSI controller.
To make HSC and DSSI devices accessible, perform one of the following
actions:
• Use this command:
$ RUN SYS$SYSTEM:CONFIGURE/DETACH
This makes the devices accessible without rebooting the system.
• Reboot the system setting the STARTUP_P1 system parameter to "".
• Reboot the system with the VAXCLUSTER system parameter set to 1
or 2.
4.5.4 Booting While Displaying Startup Procedure Commands

procedure, or when troubleshooting startup problems—it is helpful to display the
startup commands as they are executed.
How to Perform This Task
1. Follow the instructions for performing a conversational boot in one of the
following manuals:
• On VAX systems, refer to the most recent versions of the OpenVMS
VAX Upgrade and Installation Manual and the upgrade and installation
supplement for your VAX computer.
• On Alpha systems, refer to the most recent version of the OpenVMS
Alpha Upgrade and Installation Manual.
2. At the SYSBOOT> prompt, enter the following command:
SYSBOOT> SET STARTUP_P2 "YES"
3. Enter the following command to continue booting:
SYSBOOT> CONTINUE
